What size breakers are commonly found in small air conditioning units and clothes dryers?

Small air conditioning units and clothes dryers typically require larger breakers due to their significant electrical demand. These appliances can draw substantial current when operating, especially during startup when they require a higher amperage. The standard breaker size for many residential clothes dryers is often 30 amps, which can safely handle the load to prevent tripping under normal operating conditions.

Similarly, small air conditioning units also commonly use 30 amp breakers, allowing them to handle both their running current and any additional surge current that occurs when the compressor starts. Thus, 30 amp breakers are the most suitable and frequently used for these appliances, ensuring both safety and performance.
